To all whom it may concern;

Be it known that I, ALBERT H. SEAMON, a citizen of the United States, residing at Crockett, inthe county of'HOuston and State of TeXas, have inventedcertain new and use-V ing to provideanadjustable cotton chopper having a novel .and durable structure i'which to manufacture, vand effective inis cheap operation. Y Y l Another object of my invention is to proratio'off'speed. of travel of the chopper and the chopper mechanism remains practically c constant'regardless-of the speed with-,which the ydevice maybe moved over the ground, so

that the device'will cut effectively at all4 ro times. c c v A further'object of my inventionis-toV vide a cotton chopper of the class'described in which Dthe chopping mechanism isvertically adjustable wherebylvarious heights of Cuts may be obtained.-V

Otherxobjects and advantagesv to be de'-V rived from. the usev of my improved cottony chopper will appear -from the following-.detailed description and the claims,taken with an .inspection of the accompanying drawings, `in which: F igurey 1 is a sidel elevational view of a cotton chopper embodying the improvements of my invention; c

Fig. 2 is a top plan view of the same; Fig. 3 is a longitudinal sectional view; Fig. 4 is an enlarged disassembled perspective view of the chopper carrying frame;

Fig. 5 ig an enlarged fragmental sectional' view of one of the cutting elements of the chopper.

Referring more particularly to the drawings, wherein similarcharacters of reference designate like and corresponding. parts throughout the various views, F designates the main frame of my improved cotton chopper. The frame F includes top and bottom sections 10 and 11 substantially rec tangular in configuration and connected by front and rear corner postsk 12 and 13. A tongue 14 extends forwardly of the bottom section 11 and a draft animal may be connected to the forward end thereof.

The frame yF' ,is mounted on driving wheels 14 carried on the free ends of an axle 16said aXle being mounted in the rear corner posts 13. The axle is: preferably stationary and thewheels rotatable on the free ends thereof..

The chopping mechanism of my invention is of; thehorizontal type,fthat is, the rotary cutting elementrevolves on a horizontal axis, said aXis and shaft being vdesignated 18, having mounted thereon a sprocket 19, said sprocket being keyed to the shaft 18. A chain 20 is trainedover the sprocket 19 and over a sprocket wheel'21carried by a counter` shaft 22,mounted at one'end 'in one'of the front posts 12 and adjacent the opposite Vend 1in a bearing member 23. The rear end of the shaft 22 is provided with'a bevel gear 24, saidbevel gearmeshing with a second posed betureenthe upper andlower sectionsl 10fand'11 of the framek F at a point substantially .ini alii-rement with the longitudinal The frame 28 .is vertically movable on' the standards 31 and 32,l a lever 34 being pro# vided'ffor; this purpose. The lever 34 :is arranged longitudinally of the frame F "and is. pivoted at 35 to a standard 36 carried by the forwardportion of the top section ofv said frame, said 'lever 34 extending to the rear of the frame andconnected intermediate vits ends to the chopper frame 28 by means of a link 37. Tomaintain the adjustment of the lever I'y provide a curved rack bar 38 carried in a supporting structure 39 mounted on the rear of the top section 10 of said frame F. The lever 34 is provided with a recess 40 to accommodate the rack bar 38, a sliding catch 41 being mounted on the lever to engage the teeth of said rack bar. A spring 42 is anchored at 43 to the top portion of the structure 39, the lower end of the spring connecting with the lever 34 and servingto normally tend to maintain the same in the uppermost position. The lever 34 is manipulated by means of a pair of foot-pedals 4:5

carried by rocker arms 46, the latter Ybeingv pivoted on the aXle 16 as best shown in Fig.3.

A pair of connecting rods 4L? serveto conj nect the rocker arms 46 with the lever 34. The rocker armsllltiware disposed 0n either side'of `a`fse`at supporting standard, saidf standard having a seat5'1 on the'outer free end thereof. A diagonal brace 52 serves to reinforce said standard 50.

lThe cutting element includes a Wheel 54' keyed to the shaft 18, said Wheel'having a rim portion -55 onvvhicha plurality of cut- Fic' 5 12' v extension 071s providedoneach: ofithe felly of the'ivheel lis desi'gnated'O. and Yis.

Necessarily the l it .doesnot interfere EWith 'the proper han dling jof the draft-animals. .c The: spring 42,.- of course, tends .to yreturn thez cutter .frame` tending thcrefi om. The manner of connect-- ing the blades to therim is vbest shown in It will be noted that a threaded blades, `said" lextension passingthrough an openingl 5S` formed'in the rimf.

most satisfactory and convenient. Thusit will lbeseenthat in the provision ofzmy proved ,Y cotton chopper various, heights'of cuts may be obtained Without difculty, the operationrof .the `machine ,being suchl that to the uppermost; orinoperativetposition when the foot-pedals ,are released f From the above description taken 1n con.; nection with the accompanying drawings, itA

(opiesot patent maybe ,obtained rfer ive cents each, Yby addressing the is*y thought that arclevar and comprehensive understanding of the construction, operation and advantages of my invention may be had, and While I have shown and described' the device as embodying a specific structure, Il desire that it be understood thatsuch changes may bemadein said structureas do not vdepart from the'spirit and scope of the invention as claimed, Y y
